Many factors influence how long a drug remains in your system. Body metabolism, physical condition, state of hydration, age, frequency and method of usage and tolerance will all affect your result. If you know you are going to have a drug test the best thing you can do is stop taking the drug. You could also take your own drug test.

In general Phentermine could last in your system between 1 and 4 days.
